Abstract

Polycystic ovary syndrome (PCOS) is an endocrinopathy in reproductive-age women believed to be affected by several genetics and environmental factors or both. Different miRNAs are one of such genetic factors that their associations with PCOS have been implicated. For instance, miR-146a that is well known for strongly regulating the immune response and inflammation was upregulated in serum plasma, follicular fluid and granulosa cells of PCOS patients. Different studies have shown that genetic changes in pre-miRNA can cause change in the expression or biological function of mature miRNA. Therefore, the main aim of this study was to investigate the association of miR-146a gene variation (rs2910164) with the susceptibility to PCOS. This study consists of 180 patients with PCOS and 192 healthy women matched by age and geographical region. Genotyping were determined by using PCR-RFLP in all subjects. The genotype frequency and allele distributions of all subjects were evaluated using Fisher’s exact test directed by SPSS v.20. The genotype and allele frequencies of the miR-146a polymorphism (rs2910164) significantly differ between PCOS and healthy controls. The frequencies of CC genotype (p = .054) and ‘C’ allele (p = .0001) of the miR-146a variant indicated a significant incidence in cases compared to controls. Such association was obtained in co-dominant (OR = 3.16) and dominant (OR = 2.29) models. Result of this study can be proposed that women with miR-146a variation are at a higher risk for developing PCOS, which can be due to up-regulation of miR-146a. © 2018 Informa UK Limited, trading as Taylor & Francis Group
